The fifth generation mobile communication (5G) network has been commercialized on a large scale in the world in 2020, but the wireless communication channel as an important component is a complex and changeable environment. The signal is easy to be affected by the fast time-varying channel, serious multipath interference and Doppler frequency shift, resulting in large ISI and delay. Therefore, it is necessary to process the signal before transmission. In this paper, LDPC code is used as channel coding method to study the performance of m-ldpc code in 5G wireless channel. The simulation results show that the m-ldpc code can avoid the influence of multipath channel on the signal in 5G wireless channel.
